I am a fan of the 12x12 system and decided to purchase the 6x8 albums and protectors to do an album for each of my kids. I held out for the Becky Higgins brand once they were announced, as I had heard that other brands had wider pockets and I preferred the pockets which would fit the Becky Higgins brand cards. When I finally received them, they were also too wide! I have no idea why, but the 6x4 pockets and 3x4 pockets are wider than they are in the 12x12 protectors, and the cards move around in them quite a bit, often poking out the top. I am disappointed as I really thought they would fit nicely like the 12x12 albums.
